This lightweight, UL/CSA approved gauge will give precise air control, especially important with waterborne materials. • Accuracy to +/_.5 psi • UL/CSA approved • Gauge range: 2.5 to 160 psi • Auto off after 45 seconds to conserve battery life. • Up to four_year battery life, depending on usage • Ideal for HVLP or high efficiency guns – high air flow / low pressure drop • Solvent resistant • Replacement gauge (without valve): DGI_101 (803289) • The DeVilbiss digital gauge is very simple to use. The pressure display shuts off automatically after 45 seconds to conserve battery life. Simply press the “On” button (“>”) to reactivate the display. • To see if calibration is needed, turn the gauge on when it is not pressurized. If it reads “0.0,” there is no need to calibrate. On the infrequent occasions where calibration is required, follow the simple instructions on the gauge or the package.
